China has lodged stern representation to the United States over a visit to the Taiwan region by three U.S. senators, and urged the U.S. to cease any forms of official contact with the island, Chinese Foreign Ministry spokesperson Wang Wenbin said on Monday.

U.S. senators' Taiwan visit causing instability in the region

The U.S. act is in serious violation of the one-China principle and the three China-U.S. joint communiques, Wang said. "We reject and condemn it."

The spokesperson said the U.S. should translate its pledge of abiding by the one-China principle into concrete actions.

He also urged Washington to stop sending out misleading signals to the "Taiwan independence" separatist forces and properly handle Taiwan-related issues to avoid causing further damage to peace and stability across the Taiwan Straits and China-U.S. relations.

The Taiwan Affairs Office of the State Council Monday also urged the U.S. to earnestly abide by the one-China principle and three China-U.S. joint communiques.

Spokesperson Ma Xiaoguang slammed Taiwan's Democratic Progressive Party (DPP) authority for deliberately provoking cross-strait relations and blindly seeking political manipulation amid the severe pandemic situation on the island.

"At present, the pandemic continues to worsen on the island, and the DPP authorities are ignoring the lives and health of the majority of Taiwan compatriots, deliberately provoking cross-strait relations and creating trouble," Ma said.

He added that DPP had once again exposed its intent to seek "Taiwan independence."
